摘要：In this work, we study whether labour and leisure costs reported by informal caregivers must be analysed separately, using two comparable Spanish samples, for the years 1994 and 2004. We do this since informal care introduces an additional time constraint on the individual, which complicates the usual trade-off between leisure and work. We find that labour and leisure costs cannot always be identified separately.
